The A’s home stadium bears the brand name O.co. But the team referred to it as the Oakland-Alameda County Coliseum in their game notes during the home opener Friday night against the Seattle Mariners.

The name switch prompted questions about whether the Coliseum would be looking for yet another corporate sponsor just one year into a six-year deal with online retailer Overstock.com, which gave the stadium the O.co moniker.

SMG General Manager Ron Little said the O.co name would be staying put. SMG oversees operations at the Coliseum, which includes the stadium and the Oracle Arena.

The A’s refuse to accept the O.co name, Little said. It’s a sticky issue that the lawyers for both sides — the A’s and Coliseum — are still trying to iron out.

The Coliseum and the Raiders are supposed to split the earnings from the naming deal, worth about $1 million a year. The A’s were not part of the naming rights agreement. But the A’s control concessions, pouring rights during baseball and football games and control signage within the stadium.

O.co also has to pay the A’s and the Raiders separately for any other promotion of the company’s name during games.
